Place the following aqueous solutions of nonvolatile,nonionic compounds in order of decreasing osmotic pressure. I.0.011 mol L^-1 sucrose II.0.00095 mol L^-1 glucose III.0.0060 mol L^-1 glycerin

Question

Quizplus · Accepted Answer

Osmotic pressure is directly proportional to the concentration of solutes in a solution. I. 0.011 mol L^-1 sucrose has the highest concentration of the three solutions, so it will have the highest osmotic pressure. III. 0.0060 mol L^-1 glycerin has a lower concentration than sucrose but still higher than glucose, so it will have a higher osmotic pressure than glucose. II. 0.00095 mol L^-1 glucose has the lowest concentration of the three solutions, so it will have the lowest osmotic pressure. Therefore, the order of decreasing osmotic pressure is I > III > II, which is choice letter A.
